ABSTRACT:
A reactor for processing a catalyst material comprises a reaction chamber including a support for the catalyst material. A laser radiation entry means, a gas inlet and an exhaust are provided, each in communication with the reaction chamber. The gas inlet permits entry in the chamber of an oxidizing gas which assists in processing the catalyst material when exposed to laser radiation entering the chamber. Any resulting exhaust gases are then removed from the chamber through the exhaust. A drive means is provided to move the support in a manner such that the catalyst is moved through the laser radiation. The apparatus is useful in reactivate deactivated catalysts, such as hydroprocessing catalysts.
